:I think of the degree sign not as a {{!tq|unit}} but as a {{tq|multiplicative factor}}, with the value {{math|''π''/180}}. That is, much as {{math|90''x''}} means {{math|90}} times whatever value {{mvar|x}} has, an expression like {{math|90°}} means {{math|90}} times {{math|''π''/180}}, which is {{math|''π''/2}}, and is thus converted to radians before being handed to a trigonometric function. —[[User:Quantling|<span class="texhtml"><i>Q</i></span>uantling]] ([[User talk:Quantling|talk]] | [[Special:Contributions/Quantling|contribs]]) 20:20, 1 July 2025 (UTC)
::I just published my changes before reading your reply—sorry about that. I think all of the text I removed was either redundant, or in the case of the claim that a degree sign must be suffixed to the variable symbol, sketchy. I agree completely with your view of the degree as a multiplicative factor, and the last sentence of the section mentions that still.

:This doesn't make sense to me either. I would never write {{tmath|\cos x^\circ}}, and can't remember having ever seen that notation. It's just {{tmath|\cos x}}, even if {{tmath|x}} is an angle that has been specified in degrees.
:What is fair to say is that someone should try not to write {{tmath|\cos 60}} when they mean {{tmath|\cos 60^\circ}}, because the former is potentially confusing. –[[user:jacobolus|jacobolus]] [[user_talk:jacobolus|(t)]] 03:04, 2 July 2025 (UTC)
